Letters Patent No. 95,677, dated October 12, 1869.

IMPROVED RAILWAY-CAR-BRAKB SHOE.

The Schedule referred to 11; these Letters Patent and making part Of the lame.

To all whom it may concern I Be it known that I, S. B. GARDNER, of Freeport,

in the county of Stephenson, and State of Illinois, have invented an Improved ShoeibrGarrBrakcs; and I do hereby declare that the following is a full and exact description thereof, which will enable those skilled in the art to make and use the same, reference being bad to the accompanying drawing, and letters marked thereon, making a part of this specification, in which- Fignre 1 is a perspective representation of my improved shoe. Figure 2,-a vertical central section of the same.

"The nature of the present invention consists, First, in providing the brake-block with a metal lining, to prevent it from taking fire from the friction plate, 'when heated.

Second, providing the bolt-holes through the brakeblock with metal thilnbles or linings, to prevent the bolts, which hold the-friciiolnplate to theblock, from communicating fire to the latter. as the whole is hereinafter fully described.

A represents the ordinary brake-block, and B, the

beam to which it is attached in the usual manner.

0 represents the frictioi' -plate, which has a peculiar construction, as follows:

The usual lugs F H are cast to the inner side, to separate it from the block A, but grooves G G, figs. 1 and 2 are made in .it, and recesses l I are made in the margin of the grooves, to receive the heads E E, of the bolts J, which hold it on, in order that the plate 0 may be held in place, without'subjeoting the heads of the bolts J to the wear of the car-wheels.

This method of fastening the plate 0, however, is

not novel, the detailed descriptiontl'iereot' being given,

that all parts of the shoe, as it is made, may be readily understood.

The device for preventing the block A from taking vfire by the heat caused by the 'tiiction of the car-wheel on the plate 0, consists,

First, of a metal plate, I) I, placed between the. friction-plate O and the block A.

projecting outward and under the plate D P, far

enough to be held in place, when all parts of the device are put together, as shown at fig.

Having thus described my'invention;

lVhat I claim, and desire to secure by Letters Patent of the United States, is-

' 1. In combination with the friction-plate O and block A, the plate D P, for preventing the block from taking fire, as set forth.

2. In combination with the fi'iction-plate (J- and plate D P, the-thimbles L, put around the bolts J J, as and for the purpose set forth.
